Preventing and mitigating cyberattacks is a day-to-day — sometimes hour-to-hour — is a massive endeavor for enterprises. New, more advanced techniques are revealed constantly, especially with the rise in ransomware-as-a-service, crime syndicates and cybercrime commoditization. Likewise, statistics are seemingly endless, with a regular churn of new, updated reports and research studies revealing worsening conditions. 

According to Fortune Business Insights, the worldwide information security market will reach just around $376 billion in 2029. And, IBM research revealed that the average cost of a data breach is $4.35 million.

The harsh truth is that many organizations are exposed due to common software, hardware or organizational process vulnerabilities — and 93% of all networks are open to breaches, according to another recent report

Cybersecurity must therefore be a team effort, said Scott Sutherland, senior director at NetSPI, which specializes in enterprise penetration testing and attack-surface management. 

New open-source discovery and remediation tools

The company today announced the release of two new open-source tools for the information security community: PowerHuntShares and PowerHunt. Sutherland is demoing both at Black Hat USA this week. 

These new tools are aimed at helping defense, identity and access management (IAM) and security operations center (SOC) teams discover vulnerable network shares and improve detections, said Sutherland. 

They have been developed — and released in an open-source capacity — to “help ensure our penetration testers and the IT community can more effectively identify and remediate excessive share permissions that are being abused by bad actors like ransomware groups,” said Sutherland. 

He added, “They can be used as part of a regular quarterly cadence, but the hope is they’ll be a starting point for companies that lacked awareness around these issues before the tools were released.” 

Vulnerabilities revealed (by the good guys)

The new PowerHuntShares capability inventories, analyzes and reports excessive privilege assigned to server message block (SMB) shares on Microsoft’s Active Directory (AD) domain-joined computers. 

SMB allows applications on a computer to read and write to files and to request services from server programs in a computer network.

NetSPI’s new tool helps address risks of excessive share permissions in AD environments that can lead to data exposure, privilege escalation and ransomware attacks within enterprise environments, explained Sutherland. 

“PowerHuntShares is focused on identifying shares configured with excessive permissions and providing data insight to understand how they are related to each other, when they were introduced into the environment, who owns them and how exploitable they are,” said Sutherland. 

For instance, according to a recent study from cybersecurity company ExtraHop, SMB was the most prevalent protocol exposed in many industries: 34 out of 10,000 devices in financial services; seven out of 10,000 devices in healthcare; and five out of 10,000 devices in state, local and education (SLED).
